However, police are yet to verify the claims made by Kaskar.Investigators grilling Kaskar are understood to have told the sleuths that he spoke to Dawood over phone and that he made the calls using burner phones and SIM boxes.Burner phones are prepaid phones used for a particular purpose, disposed of once that purpose is over. SIM boxes enable a caller to hide their identity and the number they are calling from. "It is suspected that they used SIM boxes to route calls through Voice Over Internet Protocol (VOIP) which confuses the monitoring, security or intelligence agencies, keeping a tab on underworld elements. All this is again subjected to verification and a thorough probe connecting the dots is underway," said a senior officer.Police are also verifying intelligence reports that close relatives ofwithout stamping their passports to avoid being tracked by intelligence agencies. "Verification is underway and soon other details will come to the fore to make a watertight case," said a senior officer.Sources said a few more arrests are likely to be made soon, but police refused to comment on the same.
